Title: Power unit
Inventor: OTSU SATOSHI
IPC: G05F1/56
Filed: 1988-12-27
Abstract: PURPOSE:To reduce the fluctuated variable of the input voltage of a stabilized circuit by setting a voltage lowering circuit in parallel between a DC power supply and the stabilized circuit and connecting a switch and a current detecting circuit in parallel and in series to the voltage lowering circuit respectively to turn off the switch at a level less than the prescribed level of the current detected by the current detecting circuit. CONSTITUTION:A current detecting circuit 10 is connected to an output terminal, and a voltage lowering circuit 11 is connected between the circuit 10 and an input terminal 5. Then a switch 12 is connected in parallel to the circuit 11 to short-circuit this circuit 11. When the current flowing through the circuit 10 has the small value, the circuit 11 lowers the input voltage of a stabilized circuit 2 down to the controllable voltage level of the circuit 2. Thus the output voltage is stabilized. While the circuit 11 is short-circuited by the switch 12 when the current flowing through the circuit 10 has the large value and the output voltage of a DC power supply is kept within the control range of the circuit 2. Then the circuit 2 stabilizes the output voltage. As a result, the fluctuated variable of the input voltage is reduced for the circuit 2.
